SAWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 262,915, dated August 2.2, 1882.

Application filed July 11, 1881. (No model.)

I of which the following is a specification.

My invention relates to sawing-machines, and i.. m0.re particularly in the nature of an improvement upon that for which Letters Patent were allowed me August 30, 1881, the object being to improve the construction of the machine there described in certain particulars, andto render the same more efficient and adapt it to use both for standing and felled timber at the convenience of the operator.

To this end my present improvements consist, first, in an improved construction of the supporting frame of the machine and its movable saw-guideway, whereby a wider range of adjustment is given to the movable guideway; second, in an improved construction of the traveler and saw cross-head, whereby the saw hasa pivotal adjustment to the saw cross-head third, in animproved construction of the supporting-legs and their mode of attachment to the frame,'whereby the frame may be secured upon the ground either horizontally or vertically for cuttin gstanding or felled timber; and, fourth, in certain minor improvements in construction and arrangement, more particularly hereinafter pointed out.

My invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of inyimproved sawing-machine as used for cutting logs upon the ground, the figure being properly a plan view of the machine.

Fig. 2 is a cross-section of the machine in said position 5 Figs. 3 and 4, plan and longitudinal sections of the traveler. Fig. 5 is a side elevation of the traveler and saw cross-head, with a cross-sectionof the front cross-bar of the frame and contiguous parts. Fig. 6 is a crossseotion of the movable guideway, taken at the slot of the rear cross-bar of the supportingframe. Fig. 7 is a plan view of the roller-carrier of the'guideway and its immediate connections. Y

The similar letters of reference in the speci fication and drawings indicate similar parts.

I employ, as in the previous invention referred to, as to which this is an improvement,

a rectangular supporting-frame composed of longitudinal bars A A and cross-bars B B, and a guideway, 0, adjustable on said supporting-frame. The guideway G is provided with the pivot-bolt as, passing through the block connecting the bars of the guideway near its rear end and through the slot 8 of the cross-bar B, and thus held adjustably by the thumb-nut n, all as described in said former patent. In my present improvement Iprovide a similar connection between the guideway and forward cross-bar, B, of the frame, and for this purpose I form a slot, 8, in the crossbar B, attach a connecting-block, 0, to the under side of the guide-bars, and pass abolt, y, through this block and through the slot s of the cross-bar B, and secure by a thumb-nut, n. In order to permit adjustment of the guideway G in positions at an angle with the cross-bars, the block 0 is provided with a slot for the bolt y, which slot is long in the direction of the guideway O, as shown in Fig. 5. The two bolts 00 and yfurnish the means, therefore, of adjusting the guideway to any desired angle upon its sup-- porting-frame. The forward end of the guideway 0 is furnished with a cleat and supporting-rollers to run upon the cross-bar B, and also with a tongue, 73, to extend forward under the cross-bar B and retain the guideway in its horizontal movements.

The traveler or cross-head D, of the form shown in Figs. 3 and 4, is a casting, preferably of malleable iron, and consists substantially of a rectangular piece, 0?, somewhat narrower than the space between the guide-rails, with a sort of rectangular loop, I, at each end at the under side. In these loops are pivoted vertically wheels to w, to run between the guide-rails, which are preferably of hard wood, and at the line of the wheel-pivots ears d (1 project laterally from the part (I, as retaininglugs above .and below the guide-rails. This constitutes the traveler or cross-head proper,

and upon it is fastened the head D which contains the saw, the mode of fastening being as follows: The eyebolt e, to which, the manipulating-handle H is attached, extends through the head D, forming a pivot-connection for that member, and is firmly seated and held by suitable nuts in the part D, as shown in Fig. 4. Other bolt-apertures, f f, are provided eye or loopj of the bolt.

in the parts D and D, by which other boltconnections may be made to secure the parts firmly together, as is desirable when used for felling standing timber; but when used for cutting horizontal logs the pivot-connection is alone used.

The mode of mounting the legs on the frame is as follows: A shallow groove, 9, to fit the leg.

h, is cut across the outer surface of the bar A, and the bolt 5 is inserted through the bar A at the center of the shallow groove, and a shallow cross-recess is provided for the large The bolt is held by a thumb-nut, 70, at the opposite side of the bar A. The leg It being inserted through the eye j and the bolt being drawn in by its thumbnut is, the leg is drawn into and held tightly in the groove and securely and stiffly held against the bar A. This mode of attachment, as will be readily perceived, enables me to use the legs h upon one side of the frame as basesupports when the structure is turned on its side, and the stifi'ness of the connection is very favorable to maintaining the structure upright when used, as shown in Figs. 1 and 2. To further this use and retain the structure in position on the ground, I provide the legs with side spurs, m, at their upper extremities, which, being driven into the ground, securely hold the machine in position.

Theoperation of the machine in sawing standing timber is the same as already described in my said former patent; but when itis desired to'cutlogs upon the ground the machine is placed upon its side in proper relation to the log, the spurs m driven into the ground to hold the machine, and the guideway G adjusted by means of its bolts on and 1 to the exact position desired, the t'astenings f f detached, and the head D allowed to swing pivotally upon the traveler D. The saw is placed upon the log, as shown in Fig. 1, with a weight, 2, upon it,

porting-frame capable of being used both in a horizontal and a vertical position, in combination with a guideway provided with means for adjusting and retaining it at any desired position or angle upon said supporting-frame, a cross-head or traveler operated manually in said guideway by a handle, and a crosscutsaw provided with means for securing it pivotally or rigidly to said cross-head or traveler, as desired, substantially as and for the purpose specified.

2. The traveler D, constructed as shown, in combination with a head, D, for containing the saw, the said head being provided with both a pivotal and a rigid adjustment to the traveler, to be used alternately, substantially as set forth.

3. The combination of the frame composed of bars A A and cross-bars B. 13, provided with slots 8 and s, respectively, in combination with the guideway 0 its slotted block 0, and connecting-boltsm and 11, substantially as specified.

4. In combination with a sawing-machine adapted to alternate use, as described, the legs it, provided with lateral spurs m,substantially as and for the purpose specified.

In testimony whereofl have hereunto set my hand in the presence of two subscribing witncsses.

JOHN AUGSPURGER.
